None of my RAM will run at advertised speeds?

[Telebubbies]

Hey guys. So I have a MSI Z390 A pro motherboard, i5 9600k CPU, and 2x8gb of Corsair vengence 3200mhz cl16 RAM. My RAM is always defaulting to 2133mhz. When I try to XMP it, it changes it to 1.35V in the motherboard and 3200mhz. But Windows constantly bluescreens and wont load at all. Always a different blue screen error. I can make the RAM work at 2666mhz at 1.35V.. Why can't it work at 3200mhz and be stable? 

I had the same issue with a pair of 2x8gb hyperx 2666mhz RAM. This corsair RAM was to replace this one. The HyperX would never go to 2666mhz, and would always stay at 2133mhz. If I had changed anything for the hyperx to higher than 2133mhz, then my PC would just say that my overclock settings have failed after rebooting from BIOS.

 

Any tips or suggestions?

Thanks

Are the two RAM sticks in slots 2 and 4?

Also, are you running the latest BIOS?

Verify that all the timings are properly set according to XMP.

Is the ram on the qvl?

Yes. They are in the correct DIMM slots and I do have the latest BIOS version

All memory timings is correct to what corsair says the RAM should run at.. But I still get instant blue screen.

What does qvl mean?

[Fasauceome]

Increasing ram voltage to maybe 1.4 could help

Qualified vender list.

On the support page of the motherboard should have a page for for proven ram compatibility

I did increase voltage to 1.4V and ran a windows memory diagnostics test. It detected an error and said I have a hardware issue only 6% into the standard scan. Not sure what to do now.. These blue screens are so annoying and could lead to data loss eventually

No no that can damage skylake IMC, run Memtest 86 on each of the sticks. No failure? Well poop could be a fault in the board or CPU IMC cannot handle it... OwO

Note, I didn't say to increase the IMC voltage.

Hey. So I can get my system stable if I underclock to 2666mhz and stay at 1.35V. The timings are 16-18-18-36. Would it be worth changing some of the timings? I am thinking of 15-16-16-36 but I am kinda scared to touch the timings since I am not that familiar with them

the lower the better, just try to get away with whatever you can

 

but you can do more than 1.35 volts and try for higher frequency. Like I said, 1.4 is good, and generally up to 1.5 is very safe for ram.

Nope no no Intel have verified that the DDR3L compatible 6th gen Skylake was easy to damage with standard 1.5v DDR3-RAM sticks long term. IMC will be affected by DRAM voltage and permanent and long term usability of the chip will be at risk! :I

good thing we are not using skylake or DDR3

 

you are the first person I have ever heard say that DRAM voltage is bad for the IMC long term, curious where you learned this

Intel warned people when Skylake launched with DDR3L compatible boards, all new series even 10th gen is based on Skylake! DDR4 is more power efficient and just because the mobo lets you set it to 1.4v or 1.5v doesnt mean its safe...

 

Edit: https://en.wikipedia.org/wiki/DDR4_SDRAM

Default for DDR4 is suppose to be 1.2v and 1.35v is for DDR3L which is maximum Intel say was safe!

@Jurrunio knows a couple things about overclocking, might be able to corroborate?

 

You are the only person who has ever said that memory voltage within 1.5 volts will damage a.memory controller, every overclocking guide I've ever seen has said that it is quite safe. I would like some proof of this IMC degradation.

In an interesting report by Toms Hardware (Via KitGuru), it turns out that using DDR3 RAM at its stock settings could actually be detrimental for the health of your processor.

This is not proof

 

Stop equating coffee lake to skylake, they do not have the same memory controller. Stop equating DDR3 to DDR4, they do not work the same way.

 

This link is only proof of your original claim, not proof that 1.4 volts on this configuration is harmful. I don't care about 6th gen, and I don't care about DDR3L, neither is relevant.

 

Please only respond with a link that shows IMC degradation on coffee lake with voltages in excess of 1.35 volts.

Have Intel said they support DDR4 at 1.5v anywhere? If yes please show us proof of this because the arcitecture their CPUs have not changed much at all...

Clearly states DDR4-2666MHz(default is 1.2v tough some sticks go as far as 1.35v) as max anything over is overclocking it and its IMC which Intel have warned mainly about voltage could be harmful. It may work now sure but if 1.4v is safe long term is not certain how ever OP should at the very least not go over 1.4v with furter testing... I am also fairly sure OP might have gotten a chip with poor IMC out of box here maybe unless the RAM is defective since it maxes out at 2666MHz which Intel stated as max?

 

Intel promised no higher than 2666MHz if it doesnt work over that you are out of luck...

Yeah they also allow 1.52V in the VID table. I dont give a damn about safe voltage recommended by Intel. I do know people running.over 1.6V memory voltage with DDR4 on Skylake and later architectures without getting unstable over time.so this certainly.isnt a problem.for.OP:s DDR4 system

 

As for 1.5V DDR3 on Skylake, I dont know. I suspect it could be a problem of on die termination or other resistor not being set properly.

Not about promises. Safety and chip lifespan is what you mentioned. Obviously if your ram is not stable you need to increase the voltage. Your original response was that it was not safe, you never said it wasn't allowed.

 

Intel spec can get stuffed, it means nothing when talking about overclocking. We are exclusively discussing memory overclocking.

Its quite clear here that

A. OP lost the silicone lottery on the IMC and got a chip that can ONLY GIVE WHAT INTEL PROMISED (2666MHz) or...

B. the DDR4 sticks are defective and should be RMAd best choice here is a memtest 86 on both of them to verify they arent defective or...

C. Motherboard compatibility issue? That sucks but can happen...

OP just has to increase the voltage. You have failed to prove that it is not safe to do that.

or they're just not on the QVL
